Silver (Ag)-based materials have shown great application potential in the oxygen reduction reaction (ORR) and hydrogen peroxide (H₂O₂) detection. The porous structures of Ag have attracted a lot of research interest due to their large specific surface area and high electrochemical activity. In this work, nanoporous Ag structures composed of nano-sized particles were prepared by a one-step pulsed laser deposition (PLD) under controlled background gas pressure. The porous PLD-Ag showed a high ORR performance (E_onset: 1.007 V vs. RHE, E_1/2: 0.863 V vs. RHE), high sensitivity (613.1 μA cm⁻² mM⁻¹ at −0.2 V vs. SCE) and selectivity for H₂O₂ detection. The PLD technique provided a new, yet universal approach to producing high-performance, metal-based electrochemical electrodes.

纳米多孔银使用脉冲激光沉积进行高性能的氧还原反应和过氧化氢感测。

银（Ag）基材料在氧还原反应（ORR）和过氧化氢（H ₂ O ₂）检测中显示出巨大的应用潜力。Ag的多孔结构由于其大的比表面积和高的电化学活性而吸引了许多研究兴趣。在这项工作中，在受控的背景气压下，通过一步脉冲激光沉积（PLD）制备了由纳米级颗粒组成的纳米多孔Ag结构。多孔PLD银显示出高的性能ORR（Ë_发病：1.007 V VS RHE，。Ë _1/2：0.863 V VS RHE），灵敏度高（613.1μA厘米^-2毫^-1处为-0.2V与。SCE）和H ₂ O ₂检测的选择性。PLD技术为生产高性能，基于金属的电化学电极提供了一种新的通用方法。
